Incoming webhooks are a great way to get nicely presented information to your teams. While software and service providers have the ability to create connectors for teams, the current list of connectors not huge, though it does contain most of the big services such as Twitter, GitHub, JIRA, Trello etc. I have no doubt that the list will grow over time, but for now, the ability to integrate other sources of data via webhooks makes it relatively easy to bring timely information into your messaging environment.
